Comparisons of transverse sections in two lower internodes of two varieties under two nitrogen management practices. Transverse sections of the 1st internode under FFP (A) and OPT (B) in YJRZ. Transverse sections of the 2nd internode under FFP (C) and OPT (D) in YJRZ. Transverse sections of the 1st internode under FFP (E) and OPT (F) in YZ889. Transverse sections of the 2nd internode under FFP (G) and OPT (H) in YZ889. Scale bars indicate 50 μm. LVB, large vascular bundle; SVB: small vascular bundle; MT, mechanical tissue; PC, parenchymal cell; SC, sclerenchyma cell; EP, epidermis.
